Abstract
A venturi driven differential injector for fluid mixing having a constricting primary fluid inlet, a throat section and a diverging discharge outlet. A secondary fluid is pulled into the forward portion of the discharge outlet, through at least two annular recessed grooves, by suction action produced by the primary fluid of the venturi. A plurality of channels feed the secondary fluid into the recessed annular grooves. The venturi ports are connected to a secondary fluid injection port via an injection annulus.
Claims6
A differential injector for mixing in a flow device comprising:
- a substantially cylindrical fluid flow body having a venturi disposed therein and first and second wall portions therein, said venturi being disposed and aligned concentrically with said cylinder, for providing primary fluid flow through said venturi, the venturi having an inlet port and an outlet port;
- a secondary fluid port for supplying a plurality of fluids for mixing with the primary fluid, said secondary port being disposed within said first wall portion of the substantially cylindrical fluid flow body, for delivering secondary fluid to a plurality of flow channels, said channels being disposed within said second wall portion of the substantially cylindrical fluid flow body, and disposed in parallel arrangement with respect to the venturi, for providing secondary fluid along and parallel to an effluent portion of the primary fluid flow by injection.
